    Com port Serial Communication.


    I have an external Modum connected to Com1 Port on my PC. I would like to
    configure ( Baoud rate, etc.. ) the Com1 port and send out a string of characters
    to the Modum to dial out a phone number. I looked through the .NET class
    library and could not find a Class to deal with this.
    Thank you for the help.

    You'll need to either use COM-Interop with the MSComm ActiveX control or
    use the windows API directly. There's currently no direct support for
    COM ports in .NET. See:

    Hi,

    I have VB.NET example code prepared of the 3rd Edition of my book (due out
    by Feb 13). However, I suggest that you consider using MSComm (the
    Microsoft Communications control) and COM Interop. It is simple, and is
    compatible with lots of example code -- for instance the other code in my
    book, including all of the 2nd Edition.
